Try searching ST 170 for flow data.
The ZXTuner cams are unpublished, and actually they were ground for Esslinger by Web Cams. If you call them they can provide you with data. Just be sure to mention that it's a euro ST 170 (that's how it's listed in their system).
There are no cams for the SVT/ST 170 in your software. So don't bother looking.

Also some of Rob's later cams where custom spec'd by him through webcams, such as race cam, hi-torque II and high rev II cams were all later cams designed by him and not esslinger. I knew Rob well in the mid 2000's and bought alot of parts off of him including the first set of High Torque II cams.
